Electronegetivity : Tendency to attract electrons. Flourine is the most electronegative, extra e- in 2nd shell, tightly held Oxidant: oxidises something else and is reduced itself, and are strong electron takers DISSOCIATION: Seperation of ions ASSOCIATION: Joining of ions Reducdant: reduces something else and is oxidised itself, tend to be weak electron holders Balancing redox equations: Main atom, O with H2O, H with H+, e- on positive side IONISATION: Making ions (from covalent substances) 57 58 59 60 61 62 63 64 65 66 67 68 69 70 La Ce Pr Nd Pm Sm Eu Gd Tb Dy Ho Er Tm Yb 138.9 140.1 140.9 144.2 145 150.4 152 157.3 158.9 162.5 164.9 167.3 168.9 173
